My first program - Am i doing things corretly?!

Question

Hey all,

I've only been learning to program now for about a week and i just wonderd if someone wouldnt mind looking over my first program (that works!).

I just wanted to make sure i'm doing everything the way i should be (good practises etc etc).

Basicly i tend to use my PC as a DVD player. Now alot of DVD's when they finish go back to the menu system and loop the music. I currently was just using a scheduled batch file to end the task at a specific time. But i thought i would try and use what little C# i had learnt (and googled what i haddent). I created a program that lets me select a process and then specify a length of time that it will countdown to till the process ends.

As i said above it does work. But it just dosnt seem very neat. I just wonderd if i was learning the "right way" or if im just making a mess!

I know i still need to add error checking.

Thanks,

James
